본 연구는 시화호 대규모 간척사업의 개발기간에 따른 갯골의 변화양상을 원격탐사적으로 분석하였다. 간척사업 기간을 개발기, 폐쇄기, 개방기로 나누고, CORONA, Landsat 5 TM, Landsat 7 ETM+, 항공정사영상을 활용하여 각 시기별 갯골의 수, 연장, 너비, 방향 등의 변화양상을 분석하였다. 갯골의 수는 전반적으로 개발기에서 개방기까지 감소하는 추세를 보였으나 3차 갯골의 경우 1차, 2차 갯골과는 달리 유지되는 경향을 보였다. 갯골의 연장은 개발기부터 폐쇄기까지 전반적으로 감소하는 추세를 나타내었고, 개방기에 2차, 3차 갯골의 연장이 증가하는 추세를 보였다. 평균너비는 2차, 3차 갯골이 개발기에서 폐쇄기까지 감소하는 추세를 보이다가, 개방기 이후 증가하는 경향을 보인다. 갯골의 방향은 전반적으로 북서와 남동 방향을 보이지만, 폐쇄기에서 개방기로 전환되는 시점을 기준으로 장미도표(Rose diagram)의 형태가 남동방향의 빈도가 줄고 북서 방향 주변에서 집중되어 형태를 보였다. 이러한 갯골의 변화는 시화호 개발이전 안정적으로 에너지가 공급되던 환경에서 폐쇄기의 인공적인 환경변화로 인한 에너지의 차단, 그리고 다시 수문이 개방되어 갯골에 일부 에너지가 공급되는 환경변화로 인해 발생한 것으로 판단된다.
